Lub luag hauj lwm ntawm redispersible latex hmoov nyob rau hauv kev tsim kho kev lag luam yuav tsis tau underestimated. Raws li cov khoom siv dav siv ntau tshaj plaws, nws tuaj yeem hais tau tias qhov pom ntawm cov hmoov latex dispersible tau tsa qhov zoo ntawm kev tsim kho los ntawm ntau tshaj ib theem. Lub ntsiab tseem ceeb ntawm cov hmoov latex yog cov organic macromolecular polymer nrog cov khoom ruaj khov. Nyob rau tib lub sijhawm, PVA yog ntxiv raws li kev tiv thaiv colloid. Nws yog feem ntau powdery nyob rau hauv chav tsev kub. Lub peev xwm adhesion muaj zog heev thiab kev tsim kho kev tsim kho kuj zoo heev. Tsis tas li ntawd, cov hmoov latex no tuaj yeem txhim kho qhov hnav tsis kam thiab kev nqus dej ntawm phab ntsa los ntawm kev txhim kho cov cohesive quab yuam ntawm mortar. Nyob rau tib lub sijhawm, lub zog cohesive thiab deformability kuj yog qhov tseeb. qib kev txhim kho.
Lub luag hauj lwm ntawm redispersible latex hmoov nyob rau hauv ntub mortar:
(1) Txhim kho cov dej tuav ntawm mortar;
(2) Txuas lub sijhawm qhib ntawm mortar;
(3) Txhim kho cov cohesion ntawm mortar;
(4) Ua kom cov thixotropy thiab sag tsis kam ntawm mortar;
(5) Txhim kho qhov fluidity ntawm mortar;
(6) Txhim kho kev tsim kho kev ua haujlwm.
Lub luag hauj lwm ntawm redispersible latex hmoov tom qab mortar yog kho:
(1) Txhim kho lub zog khoov;
(2) Txhim kho tensile zog;
(3) Ntau qhov sib txawv;
(4) Txo cov modulus ntawm elasticity;
(5) Txhim kho lub zog cohesive;
(6) Txo carbonization qhov tob;
(7) Ua kom cov khoom ntom ntom;
(8) Txhim kho hnav tsis kam;
(9) Txo cov dej nqus ntawm cov khoom;
(10) Ua kom cov khoom muaj dej zoo heev.
